The unexpected consequences of LED lighting technology?

Technology is great - you may have felt a "the" behind it, and the word stands for "law of unintended"".

Let's talk about LED and solid state lighting! From the point of human beings have candles, gas lamp, incandescent lamp, fluorescent lamp, forward LED lighting technology era; this process is to promote the advantages of LED in energy conversion efficiency, and save energy in the past is in the form of heat is wasted. Cost effectiveness is also one of the reasons why LED lighting is favored, and its service life is much longer than incandescent bulbs.

The advantages of solid state lighting are often described in this way: compared with incandescent lamps, the same brightness can be achieved with less energy consumption, which is good news for the housewife / mistress, and also for the earth. This feature may not be good news for energy suppliers (power companies)... Just not many people will care about it? What I want to talk about is a question that is about to happen - or is already happening.

Because the use of solid-state lighting technology can achieve energy saving, money saving benefits, around the family, the enterprise and the local / central government agencies, will consider the installation of lighting equipment and more, especially in outdoor places -- because you can through the sensor to switch the control day / night.

So in fact, all of us may be able to save some money, some energy, but in the daily life can enjoy all day and night more lighting. The results of this energy suppliers should be pretty good, but to the human or the earth is not so good, for those who wish to star in no light pollution environment observation astronomers more bad news.

I do not mean to LED lighting lighting technology in the past than to save more energy, also is not to say we shouldn't use this new technology; it can achieve higher energy efficiency, it should be used, will be widely used. But at the same time, it is necessary to take appropriate control measures to avoid the waste of energy and unnecessary light damage.

It may be a basic human right to have a small hallway light at your doorstep, but from another perspective, you may be a "dark killer", or bring light to the environment. This "law of unintended consequences" reminds me of what the transistor co inventor Walter Brattain said.

The Brattain from the Baer Laboratory (BELl Labs) retired and returned to the United States Washington Walla Walla taught at his alma mater Whitman College (Whitman College), he said one of the invention of the transistor to make him regret things, this is the birth of the transistor radio products, make loud rock music all day appear in every corner of the campus.

Is it possible for LED lighting, like a transistor radio to bring a lot of noise to the Brattain, as well as some unexpected problems for humans?
